opencv2.4.10移植到hi3515c

[i=s] 本帖最后由 duhao 于 2015-6-9 11:19 编辑 [/i]

开贴之前，首先感谢9crk大哥的无私耐心的帮助，真心非常感激！！！

下面开始： 参考1：http://www.ebaina.com/bbs/forum.php?mod=viewthread&tid=4858&extra=page%3D1 参考2： http://ebaina.com/bbs/forum.php? ... mp;highlight=opencv

我用的系统是ubuntu12.04.4 64位，安装了海思3515官方配套的SDK，交叉编译的编译器环境是uclibc的编译器环境，gcc版本是4.6.3，cmake是2.8.10.1，然后新建一个build和output文件夹： root@duhao-virtual-machine:/home/study/hi-opencv-2.4.10# ls build opencv-2.4.10 output test 进入opencv-2.4.10，进行cmake-gui，然后配置是按参考2中的配置，配置如下：[attach]2474[/attach]

[attach]2474[/attach]

[attach]2475[/attach]

输出选成上面的output目录，既配置时CMAKE_INSTALL_PREFIX我设定的是/home/study/hi-opencv-2.4.10/output 之后进入build目录，开始make和make install，编译过程没有出现多少错误，记得一个，就是下面这样的： undefined reference to pthread_once'； undefined reference topthread_spin_lock'； 这样的类型的错误，好些个。 解决办法：参考一中提供的： 修改CMakeCache.txt大约195行处 //Flags used by the linker. CMAKE_EXE_LINKER_FLAGS:STRING= -lpthread -lrt 接着 make，后面好像没什么错误

最后在output里面生成 include，lib，share，LICENSE 。没有生成bin文件。： root@duhao-virtual-machine:/home/study/hi-opencv-2.4.10/output# ls include lib LICENSE share

之后进行编译测试 然后将output下生成的include下的opencv和opencv2拷贝到交叉编译器的include下 cp include/ /usr/local/hi-arm/arm-hisiv100-linux/arm-hisiv100-linux-uclibcgnueabi/include/ -r 把output下生成的lib下的文件也拷贝到交叉编译器的lib文件下 cp lib/ /usr/local/hi-arm/arm-hisiv100-linux/arm-hisiv100-linux-uclibcgnueabi/lib/ 可能还需要把output下的lib下的文件拷贝到/usr/local/hi-arm/arm-hisiv100-linux/target/lib下； cp lib/* /usr/local/hi-arm/arm-hisiv100-linux/target/lib 然后来编译参考1中给的如下人脸检测程序，编译命令如下：

arm-hisiv100-linux-uclibcgnueabi-g++ face.cpp -I /opt/opencv-2.2.4/Hi3518e/include/opencv -lopencv_highgui -lopencv_core -lopencv_imgproc -lpthread -lrt -lopencv_objdetect -o face

检测程序如下： /*Author:9crk 2014-12-24***/

include "cv.h"

include "highgui.h"

include "stdio.h"

/**for time mesurement*****/

include <sys/time.h>

struct timeval tpstart,tpend; unsigned long timeuses; void timeRec() { gettimeofday(&tpstart,0); } int timeRep() { gettimeofday(&tpend,0); timeuses=(tpend.tv_sec-tpstart.tv_sec)*1000000+tpend.tv_usec-tpstart.tv_usec; printf("use time: %uus\n",timeuses); return timeuses; } /****end**/

int main(int argc, char argv[]) { IplImage img = NULL; IplImage cutImg = NULL; CvMemStorage storage = cvCreateMemStorage(0); CvHaarClassifierCascade cascade = (CvHaarClassifierCascade)cvLoad("./haarcascade_frontalface_alt2.xml", 0, 0, 0); CvSeq* faces;

img = cvLoadImage(argv[1], 0);

timeRec(); faces = cvHaarDetectObjects(img, cascade, storage, 1.2, 2, 0, cvSize(25,25) ); timeRep(); if (faces->total == 0){ printf("no face!\n"); } cvSetImageROI(img, ((CvRect)cvGetSeqElem( faces, 0))); cvSaveImage("face.bmp", img);
cvResetImageROI(img); printf("face detected! in face.bmp!\n"); }

之后出现如下许多错误： /usr/local/arm/arm-hisiv100-linux/bin/../lib/gcc/arm-hisiv100-linux-uclibcgnueabi/4.4.1/../../../../arm-hisiv100-linux-uclibcgnueabi/lib/libopencv_highgui.a(grfmt_png.cpp.obj): In function

解决方法： 1.对于grfmt_png.cpp的各种undefined reference to，原因是交叉编译环境缺少libpng，解决办法是下载libpng，然后进行交叉编译，编译后生成include和lib文件夹，分别把include和lib下的文件拷贝到交叉编译环境的include和lib文件下，我的也就是上面的/usr/local/hi-arm/arm-hisiv100-linux/arm-hisiv100-linux-uclibcgnueabi/include/和/usr/local/hi-arm/arm-hisiv100-linux/arm-hisiv100-linux-uclibcgnueabi/lib/ 然后再进行编译，记得编译命令上加上-lpng，然后发现grfmt_png.cpp的错误都没有了。 2.对于grfmt_jpeg.cpp的各种undefined reference to，是交叉编译环境缺少了libjpeg，解决办法参考上面的1，下载libjpeg，交叉编译，拷贝include和lib文件到交叉编译环境的include和lib下，编译加上-ljpeg 3对于persistence.cpp的各种undefined reference to，是交叉编译环境缺少了libxml2，解决办法同上，编译时加上-xlm2后，这个错误就没了。

对于后面剩下的问题，发现是链接库的顺序导致的，下面是我修改了编译命令： arm-hisiv100-linux-uclibcgnueabi-g++ face.cpp -I/home/study/hi-opencv-2.4.4/output/include/opencv -lopencv_highgui -lopencv_imgproc -lopencv_core -lpthread -lrt -ljpeg -lpng -lxml2 -lopencv_objdetect -o face

顺序为： -lopencv_highgui -lopencv_imgproc -lopencv_core 编译后，错误为： /usr/local/hi-arm/arm-hisiv100-linux/bin/..b/gcc/arm-hisiv100-linux-uclibcgnueabi/4.4.1/../../../../arm-hisiv100-linux-uclibcgnueabibbxml2.so: warning: gethostbyname is obsolescent, use getnameinfo() instead. /usr/local/hi-arm/arm-hisiv100-linux/bin/..b/gcc/arm-hisiv100-linux-uclibcgnueabi/4.4.1/../../../../arm-hisiv100-linux-uclibcgnueabibbopencv_objdetect.a(haar.cpp.obj): In function cvHaarDetectObjectsForROC(void const*, CvHaarClassifierCascade*, CvMemStorage*, std::vector<int, std::allocator<int> >&, std::vector<double, std::allocator<double> >&, double, int, int, CvSize, CvSize, bool)': haar.cpp.text._Z25cvHaarDetectObjectsForROCPKvP23CvHaarClassifierCascadeP12CvMemStorageRSt6vectorIiSaIiEERS5_IdSaIdEEdii6CvSizeSC_b+0x538): undefined reference tocvCvtColor' haar.cpp.text._Z25cvHaarDetectObjectsForROCPKvP23CvHaarClassifierCascadeP12CvMemStorageRSt6vectorIiSaIiEERS5_IdSaIdEEdii6CvSizeSC_b+0x16e8): undefined reference to cvCanny' /usr/local/hi-arm/arm-hisiv100-linux/bin/..b/gcc/arm-hisiv100-linux-uclibcgnueabi/4.4.1/../../../../arm-hisiv100-linux-uclibcgnueabibbopencv_objdetect.a(cascadedetect.cpp.obj): In functioncv::CascadeClassifier::detectMultiScale(cv::Mat const&, std::vector<cv::Rect, std::allocator<cv::Rect > >&, std::vector<int, std::allocator >&, std::vector<double, std::allocator >&, double, int, int, cv::Size, cv::Size, bool)': cascadedetect.cpp.text._ZN2cv17CascadeClassifier16detectMultiScaleERKNS_3MatERSt6vectorINS_5Rect_IiEESaIS6_EERS4_IiSaIiEERS4_IdSaIdEEdiiNS_5Size_IiEESH_b+0x2b4): undefined reference to `cv::cvtColor(cv::_InputArray const&, cv::_OutputArray const&, int, int)' collect2: ld returned 1 exit status

这个问题两天还没解决，最后发现是因为编译命令漏掉了之前的-lopencv_objdetect，说来惭愧，因为无意漏掉这个导致两天没解决错误。最后还是在9crk大哥的帮助下一步一步找出问题所在的，希望大家引以为戒，平时学习做事都要细心一些。最后编译命令为：

arm-hisiv100-linux-uclibcgnueabi-g++ face.cpp -I/home/study/hi-opencv-2.4.4/output/include/opencv -lopencv_objdetect -lopencv_highgui -lopencv_imgproc -lopencv_core -lpthread -lrt -ljpeg -lpng -lxml2 -lopencv_objdetect -o face

发现没有错误了，就只有一个警告，后面发现这个警告没影响。有生成二进制文件，把生成的二进制文件face，lena.jpg,haarcascade_frontalface_alt2.xml拷贝到ubuntu下的nfs目录，同时把output下lib里面的libopencv_imgproc.so，libopencv_objdetect.so，libopencv_highgui.so，libopencv_core.so这四个文件拷贝到ubuntu下的nfs目录，把然后通过nfs挂载到开发板hi3515，到开发板端做软连接库到/lib目录下； ln -s nfsroot/libopencv_imgproc.so /lib/libopencv_imgproc.so ln -s nfsroot/libopencv_objdetect.so /lib/libopencv_objdetect.so ln -s nfsroot/libopencv_highgui.so /lib/libopencv_highgui.so ln -s nfsroot/libopencv_core.so /lib/libopencv_core.so 然后在face文件处，执行./face lena.jpg。 提醒有错误： 意思就是libjpeg.so.62没加载，libpng15.so.15没加载，libxml2.so.2没加载这样的问题。 原因是arm板上lib里面缺少这些库 解决方法： 在交叉编译环境把这三个文件拷贝到nfs下，nfs挂载到开发板后，然后在开发板作软连接，将这三个库软连接到arm上的lib下： ln -s nfsroot/libjpeg.so.62 /lib/libjpeg.so.62 ln -s nfsroot/libpng15.so.15 /lib/libpng15.so.15 ln -s nfsroot/libxml2.so.2 /lib/libxml2.so.2 再在face目录下执行：./face lena.jpg 结果没有错误，可以正常运行，生成图片文件。

到这里，就结束了，希望能给移植opencv的人提供一些帮助，尽量少走一些弯路！ 最后，再次郑重感谢9crk大哥的无私帮助。非常非常感谢。。。
